This may be more of a vague open-ended question but going to ask it anyway. To start I want to mention that I'm not looking for ideal parameters for that I have always tried to adhere to Randy's recommendations and will piggyback off the recommended ranges to this discussion

My question around parameters is whether or not specific parameters have a so called "doomsday" clocks of when problems start to emerge as a direct result of that specific parameter being out of range if it's not brought back into range within a X number of hours/days/weeks/month. (IE, if Ammonia exceed 0.1ppm get back into range within the X hours. If phosphate falls below .06 or bottoms out, you can safely go X days and correct before good bacteria dies off leading to Dynos....) . I tend to test weekly sometimes every other, so I'm just curious if between test when parameters fall out of range if there is risks waiting around for the next testing day. My main focus is Phosphate and Nitrate what i have been working to keep elevated but will open this up to all parameters. If times differ between SPS/LPS or Mix please indicate. Also, if you don't adhere to Randy's values, that fine, question can still apply based on your own personal high/low ranges,

Example of what im trying to see would be like some like, Numbers are fake

type of setup - SPS
ca - Can safely dip below target range for 2 weeks max don't ever fall below 300PPM, Above for 2 weeks max don't ever fall below 500PPM
alk - Can safely dip below target range for 2 day max don't ever fall below 7 dkh , Above 1 weeks max don't ever go above below 14 dkh

I use BRS guide for the most part. Of course there are strong opinions about that too..

My params:
Mixed reef (SPS dominant)
Salinity 35-36 ppt
Ca - 400-450 -> Trying to maintain 425
Mag - 1400
Alk 8.5-9 dKH
pH - 7.8 to 8.4 -> Anything below 7.8 and an sps frag will start peeling.
Nitrate - 5-10 ppm
Phosphates - aiming for 0.05-0.2 -> currently at .49 as I'm battling dinos
Temp 77.5 - 79

I don’t think I could attach a time frame to how fast problems could arise from being out of the norm, and the extent and type of problem will be highly variable with the parameter out of range.
